Save for Web and pasted text input focus problem

When using Save for Web from Photoshop CC 2014 (20140730.r.148 x64) with Mac OX X 10.9, if I modify the Quality value to anything other than what comes up as the default - essentially having the OS provide focus to that field, then it's impossible to paste text into the "Save As:" filename filed that comes up once I click the "Save" button. The focus stays on that Quality field and any pasted text shows up there, rather than in the filename dialog. No amount of attempting to change the OS focus to the "Save As:" field will fix the problem. If the Quality field has received focus before the Save dialog is launched, nothing can take it away.
